DivX to SWF Converter

Convert DivX to SWF Online

This tool re-encodes a DivX video (MPEG-4 ASP, usually inside an AVI file) into an SWF Flash movie — a Flash-video stream wrapped in Adobe's Shockwave Flash container. Be aware this is a legacy conversion: Adobe stopped supporting Flash Player on December 31, 2020, and blocked Flash content from running on January 12, 2021, so an SWF will not play in any current browser. It is useful only for old Flash projectors, authoring tools, or archival workflows that still expect SWF. If you just want a video that plays everywhere today, convert DivX to MP4 instead.

How to Convert DivX to SWF

1. Upload Your DivX File: Drag and drop your .divx (or .avi) clip onto the page, or click "+ Add Files" to pick it from your computer.
2. Confirm SWF as the Output: SWF is preselected; the video is encoded with the Flash codec and MP3 audio, which is what SWF playback expects.
3. Set Quality Preset or Specific File Size (Optional): Open Advanced Options to choose a Quality Preset, target a Specific file size, scale resolution with Resolution Percentage or Preset Resolutions, or cut a clip with the Time Range trim.
4. Convert and Download: Click "Convert" and download your SWF. No sign-up, no watermark.

DivX vs SWF vs MP4 — Which Output to Pick

Why This Conversion Is Re-encoding, Not a Container Swap

DivX and SWF use different video codecs (MPEG-4 ASP vs Flash video), so the file has to be decoded and re-encoded rather than simply re-wrapped. That means one round of generation loss. Keep your original DivX file if you may need a higher-quality master later, and use the highest Quality Preset if visual fidelity matters more than file size.

Frequently Asked Questions

Why would anyone still convert DivX to SWF in 2026?

Almost no one needs SWF for playback anymore — Adobe ended Flash Player support on December 31, 2020. The remaining real uses are feeding an old Flash projector, importing footage into legacy Flash/Animate authoring projects, or matching an archived asset pipeline that still expects .swf. For any modern viewing, DivX to MP4 is the right choice.

What can actually open an SWF file now?

No current mainstream browser plays SWF, because Flash Player is retired. Standalone options include the open-source Ruffle emulator (limited support for embedded video), the standalone Flash projector if you still have it, and VLC for some simple files. Interactive ActionScript SWFs often will not run reliably anywhere today.

Will I lose quality converting DivX to SWF?

Yes, some. Because the video codec changes from MPEG-4 ASP to Flash video, the file is fully re-encoded, which introduces one generation of compression loss. Choosing a higher Quality Preset or a larger Specific file size reduces visible artifacts at the cost of a bigger output.

Should I convert DivX to SWF or to MP4?

Pick MP4 unless a specific legacy tool requires SWF. MP4 with H.264 plays natively in every modern browser and on phones, smart TVs, and editors. SWF only makes sense when you are targeting old Flash software. You can run DivX to MP4 for the universal option or SWF to MP4 to rescue content that is already in SWF.

How long does the conversion take and what happens to my file?

Time depends mostly on clip length and your upload speed, since the file is processed on our servers rather than on your device. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared or made public.

Can I trim or resize the DivX before exporting to SWF?

Yes. In our testing, a short clip exports fastest when you trim it first: use the Time Range control to keep only the seconds you need, and use Resolution Percentage or a Preset Resolution to scale the frame down. Smaller dimensions and shorter runtime both keep the legacy SWF output manageable.
